Locating Seller based on partial name search

[fcclife]

Hello,

I am trying to do a search for a seller where I only have a partial name.  We can't find original purchase info yet our Vista shows a purchase.  We are trying to find seller based on info in the Vista statement.

I have searched using the Advanced Search, By Seller, but that seems to only work for exact matches.

All of the help I could find claims it could do partial, but they look like older advanced search screenshots.

So how can we do partial search on seller name?

Thanks,

Greg
